This isn't a mecha show pretending to be slice-of-life, and it's not a high school drama pretending to have robots. Gridman commits to both, and somewhere in that collision between mundane cafeteria moments and incomprehensible kaiju destruction, it finds something neither genre typically allows: real uncertainty about what's actually happening. The first three episodes feel slow until they snap into focus, and by episode six you're watching a show that knows exactly how to weaponize the gap between what Yuta sees and what everyone else sees. The fanservice is clumsy and drags momentum more than once. What matters is that the show's willing to be strange in ways most mecha anime aren't willing to risk, and it earns the weirdness by the end.

Yuta wakes up with no memory and a strange ability: he sees things nobody else can. When a robot called Gridman appears on the screen of an old computer at his friend Rikka's place, it urges him to remember his calling. Yuta has no idea what that means, and Rikka can neither hear the voice nor see the enormous, motionless monster he spots in the distance. Then a giant monster starts wrecking the city, and Gridman pulls Yuta into the digital world, sending him back out as a colossal hero ready to fight. Joined by Rikka and their classmate Sho Utsumi, he forms the Gridman Alliance to defeat the monsters and uncover whoever is behind them. The result is action-driven mecha sci-fi built around giant battles and the mystery of Yuta's missing memories.
